Bilateral ureter failure refers to the failure of ureter to develop normally when urography is performed on both sides of the ureter, which is mostly caused by obstruction, and the etiology is often stone or obstruction. Urography is mainly used to observe the inner wall and lumen of renal calyx, renal pelvis, ureter and bladder, and is divided into excretory and retrograde imaging. Excretory contrast is a method of visualizing the urinary tract by injecting iodine-containing contrast agent intravenously, which is filtered by the glomerulus and sequentially excreted into the renal calyxes, renal pelvis, ureter and bladder. When obstruction occurs, it can result in poor or even no visualization below the obstruction and enlarged fluid accumulation above the obstruction. This obstruction is most often caused by stones or tumors. Retrograde pyelography, which is invasive, can be used when patients have contraindications to excretory imaging or poor results. If the patient’s bilateral ureter does not show should consult a specialized physician for a clear diagnosis and symptomatic treatment.
